3.2 Installation You Have to Know
a
m
Installing CPU
This motherboard supports AMD® Athlon Socket 462 series CPU. Be careful of
CPU orientation when you plug it into CPU socket (with CPU Overheat Protection
function implemented, the system will be automatically powered off when the
temperature of CPU reaches to 97 degree, but it works only on Athlon
Duron CPU).
1. Pull up the CPU socket lever and up to 90-degree angle.
2. Locate Pin 1 in the socket and look for a golden arrow on the CPU upper
interface. Match Pin 1 and golden arrow. Then insert the CPU into the
socket.
3. Press down the CPU socket lever to finish CPU installation.

Installing CPU and System Fans
Plug the CPU fan cable to the 3-pin CPUFAN connector. If you have chassis fan,
you can also plug it in SYSFAN1 or SYSFAN2 connector.

Note: Some CPU fans
do not have sensor pin so
that they cannot support fan

Installing Memory Modules
DIMM slots are designed in Black which are very easy to recognize. Insert the
module straight down to the DIMM slot with both hands and press down firmly
until the DIMM module is securely in place.

connector and IDE connector. Be careful of the pin1 orientation. Wrong
orientation may cause system damage.

Connecting Front Panel Cable
Attach the power LED, speaker and reset switch connectors to the corresponding
pins. If you enable “Suspend Mode” item in BIOS Setup, the ACPI & Power LED
will keep flashing while the system is in suspend mode.
Locate the power switch cable from your ATX housing, which is a 2-pin female
connector from the housing front panel. Plug this connector to the soft-power
switch connector marked SPWR.

Connecting ATX Power Cables
This motherboard comes with a 20-pin connector as shown below. Make sure you
plug them in the right direction.

3.3 Other Installation for Your Reference
Setting CPU Voltage and Frequency
Setting CPU Core Voltage
This motherboard supports Voltage ID (VID) function to detect CPU voltage
automatically during power-on.
Setting CPU Frequency
This motherboard is CPU jumper-less design, you can set CPU frequency through
1MHz stepping CPU Overclocking in the BIOS. CPU Core Frequency = CPU FSB
clock x CPU Ratio. However, all CPU now selling in the market belong to "Fixed
Multiplier". That means users can not adjust the CPU Ratio but only change CPU
FSB clock to achieve overclocking.
BIOS Setup > Frequency / Voltage Control > CPU Speed Setup
CPU Ratio From 5.5x to 16.5x step 0.5x; 17x to 18x
step 1x
CPU FSB
(Adjustment manually)
FSB= 100MHz-255MHz by 1MHz Stepping
